The drums are attached to the hub for the wheel bearings.
SO to get them off you need to remove the 8 bolts and remove the axle assembly.
Then you can remove the small spring around the end of the axle and remove the small lock inserted into the key.
After that you can remove the axle nut and pry the axle off.
sorry the hub off.
From there you drive the wheel studs off the hub and you can them change the drums.
Thanks for responding. I have the axle assembly out, the spring off, and the the lock out of the key. How do I remove the axle nut?
simply spin it off. It should be loose enough that you can use a screwdriver to get it off. IT is normal threads.
Do I need to take the hub off of the drum to replace the oil seal and bearings?
